Devise Sendgrid和Cancancan：UserRegistrations＃create中的NameError

Question

每当我尝试在Rails应用程序中注册新用户时，我总是收到相同的错误-我使用Devise进行注册，使用CanCanCan和Sendgrid通过新用户的电子邮件发送通知邮件。

新用户可以注册，但是会出现错误：

NameError in UserRegistrations#create

Showing C:/Users/Adsidera/FreshObst/app/views/user_mailer/welcome.html.erb where line #4 raised:

  undefined local variable or method `user' for #<#<Class:0x5777fb8>:0x5bdac78>

Rails.root: C:/Users/Adsidera/FreshObst
Application Trace | Framework Trace | Full Trace

app/views/user_mailer/welcome.html.erb:4:in `_app_views_user_mailer_welcome_html_erb__1004447735_47859732'
app/mailers/user_mailer.rb:14:in `welcome'
app/controllers/user_registrations_controller.rb:7:in `create'

这是user_registrations_controller.rb

class UserRegistrationsController < Devise::RegistrationsController
before_filter :configure_permitted_parameters

def create
    super
    if @user.persisted?
        UserMailer.welcome(@user).deliver_now
    end
end


protected

# my custom fields are :name, :heard_how
def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
    u.permit(:first_name, :last_name,
    :email, :password, :password_confirmation)
end

devise_parameter_sanitizer.for(:account_update) do |u|
    u.permit(:first_name, 
    :email, :password, :password_confirmation, :current_password)
   end
 end
end

这是user_mailer.rb

   class UserMailer < ApplicationMailer
default from: "freshobstuser@yahoo.com"

    def contact_form(email, name, message)
        @message = message
        mail(:from => email, 
            :to => 'freshobstuser@yahoo.com',
            :subject => 'A new contact form message from #{name}' 
            )
    end

   def welcome(user)
       @appname = "FreshObst"
        mail(:to => user.email,
         :subject => "Welcome to #{@appname}!")
   end
 end

这也是我的github的链接https://github.com/Adsidera/FreshObst

谢谢！ 我对此感到发疯...安娜

UPDATE！

在Illusionist的建议之后，这个问题似乎已经解决了一半，现在我有了以下日志：

上一个错误的解决方案 ：上一个错误似乎是由我默认选择的yahoo.com邮件地址引起的，从我的SendGrid日志中得出：“ 550 5.7.1由于域的DMARC策略，不接受来自yahoo.com的未经身份验证的电子邮件。如果这是一封合法邮件，请与yahoo.com域的管理员联系。请访问https://support.google.com/mail/answer/2451690以了解有关DMARC计划的信息。”

然后将默认邮件地址更改为非Yahoo邮件地址即可解决此问题。 非常感谢大家！

Answer 1

尝试这个

# in app/views/user_mailer/welcome.html.erb
<td><h2>Welcome <%= @user.first_name %>!</h2></td>

和

# in app/mailers/user_mailer.rb
def welcome(user)
  @user = user
  @appname = "FreshObst"
  mail(:to => @user.email,
       :subject => "Welcome to #{@appname}!")
end

Answer 2

解决最后一个错误的方法 ：虽然这最后一个错误似乎是由我默认选择的yahoo.com邮件地址引起的，如我的SendGrid日志中所述：“ 550 5.7.1由于域的DMARC策略，不接受来自yahoo.com的未经身份验证的电子邮件。如果这是一封合法邮件，请与yahoo.com域的管理员联系。请访问https://support.google.com/mail/answer/2451690以了解有关DMARC计划的信息。”

然后将默认邮件地址更改为非Yahoo邮件地址即可解决此问题。
